Summary: Each morning, your brain undergoes a precise sequence to shift from sleep to wakefulness, reorienting you to the world.

They found that even when people misjudged someone’s emotions, their brain still carried a latent signature …

Summary: The brain constantly toggles between focusing on external sensory information and internal mental representations like memories, plans, and thoughts. This seamless switching is crucial for adaptive behavior, yet the underlying mechanisms remain poorly understood. Recent research highlights both shared and distinct neural networks for external and internal attention, revealing costs and trade-offs when shifting between them. Understanding these processes …
